Smart Disk Space Analyzer for macOS

简体中文 | English

Features

• Disk Overview — Real-time disk capacity visualization with donut chart, directory drilldown, and multi-volume support
• Dirty Data Detection — Rule-based engine with 30+ built-in rules covering dev caches, build artifacts, package manager caches, system logs, and app leftovers
• Duplicate File Finder — Progressive 3-stage detection: size grouping → first-block hash pre-filter → full-file SHA256 confirmation
• Safety-First Cleanup — Every item tagged with a safety level (Safe / Cautious / Dangerous) with clear explanations, trash-by-default deletion
• Native Performance — Pure SwiftUI with zero third-party dependencies, built for Apple Silicon

How It Works

Scan Flow
─────────────────────────────────────────────

 Quick Estimate ──▶ Dirty Data Detection ──▶ Duplicate Detection
 (rule paths,     (30+ rules + app         (size → hash → SHA256
  1-3 seconds)     leftover scanning)       progressive confirm)

Each scan result includes:

• Safety level with color-coded badge
• Human-readable explanation
• Recommended cleanup action (trash / delete)

Requirements

• macOS 14.0 (Sonoma) or later
• Xcode 16.0+
• Full Disk Access permission (System Settings → Privacy & Security)

Build

git clone https://github.com/ArtLjn/DiskPulse.git
cd DiskPulse
open DiskPulse.xcodeproj

Build and run via Xcode (Cmd+R). On first launch, grant Full Disk Access when prompted.
